MP Board · Class 9 · Science · Matter in Our SurroundingsWhat is meant by the latent heat of vaporization?
Step-by-Step Solution
The latent heat of vaporization is defined as the amount of heat energy required to convert 1 kilogram of a liquid into gas at its boiling point under atmospheric pressure without any rise in its temperature. Particles in steam at 100 °C have more energy than water at the same temperature due to absorbing this latent heat.
